The general objective of this study was to compare the precise grasping behavior and intermanual differences in performance between three Pan paniscus and five Homo sapiens in grasping small objects. We compared the temporal pattern of two submovements of consecutive grasping cycles, the (visuomotor) reaching and the (sensorimotor) grasping. Both species were similarly successful in this task, they showed a behavioral right-hand preference and preferred specific types of grips. Bonobos required… 

Versatile grasping ability in power-grip actions by tufted capuchin monkeys (Sapajus spp.).

Findings clarify the extent to which manual dexterity and cognitive abilities can be expressed in the grasping tasks of highly manually skilled primate species.

Manual Function in Cebus apella. Digital Mobility, Preshaping, and Endurance in Repetitive Grasping

It is concluded that precise finger coordination is more effortful and less well coordinated, and the coordination is less lateralized, in capuchins than in catarrhine primates.

Behavioral and functional strategies during tool use tasks in bonobos.

Bonobos were able to develop in-hand movements similar to humans and chimpanzees, demonstrated dynamic manipulation, and they responded to task constraints by selecting and modifying tools appropriately, usually before they started the tasks.

Hand preferences for bimanual coordination in 29 bonobos (Pan paniscus)

Handedness for Unimanual Grasping in 564 Great Apes: The Effect on Grip Morphology and a Comparison with Hand Use for a Bimanual Coordinated Task

Right hand bias for reaching is found and the ratio of subjects with consistent right compared to left hand use was more prevalent in bonobos, chimpanzees and gorillas but not orangutans, suggesting some measures may be more sensitive in assessing handedness than others.

Grasping behavior in tufted capuchin monkeys (Cebus apella): grip types and manual laterality for picking up a small food item.

Analysis of prehension in 20 tufted capuchins in a reaching task requiring individuals to grasp a small food item fixed to a tray revealed that precision grips were as efficient as power grips; for precision grips, the left hand was faster than the right hand; and for power grips, both hands were equally quick.

Hand Preferences for Bimanual Coordination in 77 Bonobos (Pan paniscus): Replication and Extension

It is suggested that, despite particular features in terms of proximity to humans, language and bipedalism, bonobos do not display a laterality that is more marked or more similar to human handedness compared to that of other nonhuman primate species.

Grip morphology and hand use in chimpanzees (Pan troglodytes): evidence of a left hemisphere specialization in motor skill.

The cumulative results indicate that chimpanzees show a left-hemisphere asymmetry in motor skill that is associated with the use of precision grips.

Manual function and performance in humans, gorillas, and orangutans during the same tool use task.

Comparing the manual function and performance developed by humans, gorillas and orangutans while performing the same experimental tool use task highlights other ways in which humans' manual dexterity differs from that of other species and emphasizes the distinct manipulative function of orangutan.



Grasping techniques and hand preferences in Hominoidea

The method was focused on ad libitum picking up differently shaped and very small objects without task-specific set ups and a comparable experimental set up for both, apes and humans.

No single skeletal feature can be safely relied upon as an indicator of distinctively human capabilities for precision gripping or tool making in fossil hominids.

Hand preference in a captive island group of chimpanzees (Pan troglodytes)

The results from these tests on this group of five chimpanzees suggest that cerebral morphological asymmetries in the chimpanzee are not associated with motor dominance as reflected in handedness, with no trends apparent for the group as a whole.

Effect of posture on hand preferences during experimental food reaching in bonobos (Pan paniscus).

The effect of posture on hand preferences was examined in an experiment with 5 bonobos and all animals showed an increasing trend toward left-handedness while shifting to a bipedal posture from a seated posture by way of a quadrupedal posture.

Precision grips in young chimpanzees

Evidence is provided that young chimpanzees preferentially use a true precision grip to prehend small and very small objects.

Different hand postures for pounding nuts with natural hammers by wild chimpanzees

It is proposed that the hand of the chimpanzee is already morphologically able to perform most tasks attributed to Homo habilis.

Behavioral laterality in captive bonobos (Pan paniscus).

Behavioral laterality was studied in a captive group of 11 bonobos and a significant shift toward greater right-hand use was found when subjects were required to maintain a bipedal, rather than a quadrupedal, posture.

Knuckle‐walking and the evolution of hominoid hands

The knuckle-walking hands and plantigrade feet of African apes are both morphologically and adaptively distinct from those of Pongo, their nearest relative among extant apes, and these features are associated with a common adaptive shift to terrestrial locomotion and support placing chimpanzees and gorillas in the same genus Pan.
